1. Bellwork: January 27 Copy and define the following words. – They’re: __________________________ – Their: ____________________________ – There: ____________________________

2. CO: I will define taxonomy, recognize the importance of a taxonomic system, and categorize organisms into domains. LO: I will write notes. I will sort organisms with a partner. I will collect bacteria with a partner.

3. Classification is the grouping of objects or information based on similarities.

4. Name 5 things that people classify on a regular basis?

5. For 1 of your 5 things, explain how it’s classified?

6. Taxonomy is the science of grouping and naming organisms. In other words, taxonomy is the process of classifying and naming biological (living) organisms. In Biology:

7. 7 Domain Kingdom Phylum Class Order Family Genus Species BROADEST TAXON Most Specific copyright cmassengale The major classification levels, from most general to most specific A group at any level is a taxon.

10. Let’s look at some animals

11. Devil Cat

12. Ghost Cat

13. Mountain Lion

14. Screaming Cat

15. Puma

16. Florida Panther

17. Cougar

18. There are at least 50 common names for the animal shown on the previous 7 slides. Common names vary according to region. How could we fix this problem?

19. 19 Confusion in Using Different Languages for Names copyright cmassengale

20. 20 Scientific Names are Understood by all Taxonomists copyright cmassengale

21. Taxonomists give a unique scientific name to each species they know about whether it’s alive today or extinct. The scientific name comes from one of two “dead” languages – Latin or ancient Greek.

22. The genus name is written first (always Capitalized). The species name is written second (never capitalized). Both words are italicized if typed or underlined if hand written. Example: Felis concolor or F. concolor Which is the genus? The species? Binomial Nomenclature a two name system for writing scientific names. Turdus migratorius Turdus migratorius a

23. 23 Binomial Nomenclature Which TWO are more closely related? copyright cmassengale

24. Now that you know why we need to classify organisms and how to name them; we are going to learn about each taxon in detail.
